MIOCENE MOLLUSCA AND CRUSTACEA. 13 
Formation and localities: Mr. Conrad’s original specimens are cited as 
from the Choptank River, in Maryland. In New Jersey they appear to 
come from Shiloh, Jericho, and near Bridgeton, and at the two former 
localities are common. I have received them from the collection at Rutgers 
College and from the National Museum—the latter having been collected 
by Mr. Frank Burns. 
Family TEREBRID.

“Subulate, whorls with a revolving impressed line below and near the 
suture; beneath this line the whorls are convex; ribs longitudinal, curved, 
acute, dislocated by the impressed line; revolving lines minute, crowded, 
obsolete; columella sinuous. Length, 14 inches. 
“Differs from Cerithium dislocatum Say, in wanting the distant revolv- 
ing lines, and the small dislocated portion of the ribs are [have] not a tuber- 
cular form; the aperture is longer and narrower.” (Conrad.) 
The resemblance between this and 7. dislocata Say is so great as to 
require a close scrutiny to distinguish between them. The difference 
between the ‘revolving [spiral] lines” of Say’s species and the extremely 
fine spiral lines of this one being the most important distinction; while the 
dislocation of the vertical ridges here can hardly be said to amount to an 
interruption, as it often does in Say’s species. 
Formation and locality: Only four specimens of this form have been 
obtained in the collections from the Miocene marls at Jericho, N. J. These 
belong to the National Museum collections.
